It sounds like a dead short. I need to know what fuse you are referring to. Also, check the wiring near the fuse box to see if anything is damaged as far as wiring or the connectors where the fuse sits.
Here is a link for testing wiring. You may find it of interest.
Let me know if you find anything or have other questions.
Take care and God Bless,
